PPE Stage 1 Performance Camshaft (Alternate-Fire Keyed) for 2001–2016 GM 6.6L Duramax

Description

The PPE Stage 1 Performance Camshaft – ALT-Firing changes the cylinder firing sequence to 1-5-6-3-4-2-7-8. This alternation reduces the stress exerted on the crankshaft and prevents crankshaft failures which are commonly seen in high-performance applications. With a moderate intake/exhaust duration and a .460’’ intake/exhaust valve lift, this camshaft works great with stock or performance tune. Each camshaft is forged with high-tensile chromoly steel, precision ground to extremely tight tolerance, and then carburized and quenched to achieve 60+ HRC surface hardness. It also features a slotted gear alignment pin for increased durability
